A12 kg barrel is pulled up by a rope. the barrel accelerates at 1.2 m/s2. find the force exerted by the rope. show all your work.

F = 132N

Explanation:

Let the pulling force be F

Given the mass of the barrel is 12 Kg and The acceleration is 1.2 m/

We know that Net Force =

Now net force = F - mg

F - mg = ma

F = mg + ma

F = m(a+g) =  

Note that there will be a downward force acting on the body which is equal to mg

what is the question because that is not a question.

c) up

hope this
